Prolonged post-vagotomy gastric atony treated by oxytocin.
Persistent and complete post-vagotomy gastric atony was treated in 3 patients by intravenous infusion of oxytocin. Despite failure of both conventional treatment with gastric aspiration and intravenous fluids or jejunal feeding, as well as the reported trials with bethanechol chloride and metaclopramide, these patients promptly responded to oxytocin. It appears that the latter may represent a solution to this uncommon but recalcitrant complication of peptic ulcer surgery.

Factors influencing acute thrombus formation on carotid artery vascular grafts.
Scintillation camera imaging of 111Indium-labeled platelets has been used to measure acute thrombus formation on modified expanded Teflon (ePTFE) vascular grafts (Gore-Tex, 4.0 mm i.d. x 3-5 cm in length, W. L. Gore and Associates, Inc., Flagstaff, AZ) placed in the carotid arteries of normal baboons. Platelet deposition plateaued over 2 hr postoperatively and occurred primarily at the graft-vessel anastomoses. A positive correlation was found between the circulating platelet count in individual animals and the extent of early platelet thrombus deposition. Unmodified ePTFE grafts accumulated 4.6 +/- 1.2 x 10(9) platelets per graft, or 2.3 +/- 0.71 x 10(9) platelets per anastomosis. Acutely, platelet accumulation was reduced versus control graft results by coating the graft lumenal surfaces with a smooth layer of silicone rubber polymer (0.60 +/- 0.19 x 10(9) platelets per anastomosis; P less than 0.02) but not by coating the grafts using a plasma polymer based on methane, which did not modify graft texture (8.2 +/- 1.7 x 10(9) platelets per graft; P greater than 0.10). The benefit of the silicone rubber coating persisted for at least 48 hr. However, longer term patency was not preserved because 10 of 12 grafts placed had failed within 1 to 2 months.

Aortocaval fistula due to rupture of abdominal aortic aneurysm.
Two patients with spontaneous aortocaval fistula due to a ruptured aortic abdominal aneurysm are described. This accident is one of the rarest complications of such an aneurysm and is a severe surgical emergency with widely varying symptoms. Although its recognition should be obvious, it poses both diagnostic and therapeutic problems. One of our patients survived following 45 days of hemodialysis treatment.
